EP-4739097-A1 - SYSTEMS AND METHODS FOR RAISING A CART IN A MODULAR GROW TOWER

Abstract

The present disclosure presents systems and related methods for raising a cart in a modular grow tower assembly. One such system comprises a modular grow tower assembly including a plurality of body frames and a plurality of lift frames. The body frames are configured to support a plurality of carts moving along a path from a top end to a bottom end of the modular grow tower assembly. A harvest frame is positioned adjacent to one of the lift frames. A raising lift mechanism is configured to pull a cart from the modular grow tower assembly into the harvest frame. The raising lift mechanism comprises fork members that are configured to engage wheels of the cart. The raising lift mechanism is further configured to move vertically within the harvest frame to position the cart for subsequent harvesting and reinsertion into the modular grow tower assembly.

7. 7. The method of claim 6, further comprising detecting, by a controller, if crop materials in the cart are ready for harvesting and adjusting movement of the cart and/or lighting, watering, nutrient delivery, and/or other growth conditions of the crop material based on the detected readiness.
8. 8. The method of claim 6, wherein the path comprises a serpentine path.
9. 9. The method of claim 6. w herein the raising lift mechanism is configured to rotate about a z-axis to overturn the cart for harvesting, sanitizing, and/or seeding.
10. 10. The method of claim 6, further comprising harvesting the cart by removing crop materials from the cart.
11. 11. The method of claim 10, further comprising sanitizing the cart after harvesting is performed.
12. 12. The method of claim 10, further comprising reseeding the cart after the crop materials are removed.
13. 13. A raising lift mechanism for use in a modular grow tower assembly, comprising: a base frame; a rail having a first end and a second end, each end including fork members configured to engage wheels of a cart; rollers on the fork members configured to interact with a guide in a harvest frame at a termination point of a movement path of the cart; wherein the rail is rotatably mounted to the base frame and is configured to move longitudinally between an extended position, for engaging a cart, and a retracted position, for pulling the cart into the harvest frame; and the raising lift mechanism being further configured to move vertically within the harvest frame to facilitate harvesting, sanitizing, seeding, and reinsertion of the cart into the modular grow tower assembly.
14. 14. The raising lift mechanism of claim 13, wherein the fork members include a first fork and a second fork configured to securely hold the wheels of the cart during vertical movement.
15. 15. The raising lift mechanism of claim 13, wherein the rollers on the fork members are configured to engage guides in the harvest frame to control a rotational movement of the rail.

Description

SYSTEMS AND METHODS FOR RAISING A CART IN A MODULAR GROW TOWER CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to co-pending U.S. provisional application entitled, “Systems and Methods for Raising a Cart in an Assembly Line Grow Pod,” having application number 63/512,132, fded July 6, 2023, and U.S. provisional application entitled, “Systems and Methods for Providing a Modular Grow Pod,” having application number 63/512,129, filed July 6, 2023, each of which is entirely incorporated herein by reference. TECHNICAL FIELD [0002] Embodiments described herein generally relate to systems and methods for raising a cart in a modular grow tower assembly and, more specifically, to a raising lift mechanism for raising a cart in a modular grow tower assembly. BACKGROUND [0003] While crop growth technologies have advanced over the years, there are still many problems in the farming and crop industry today. As an example, while technological advances have increased efficiency and production of various crops, many factors may affect a harvest, such as weather, disease, infestation, and the like. Additionally, while the United States currently has suitable farmland to adequately provide food for the U.S. population, pets, and livestock, other countries and future populations may not have enough farmland to provide the appropriate amount of crops for these purposes.
